Description: Image water marking using Stationary Wavelet Transform with 3-level decomposition.
The problem with DWT is lack of shift-invarience and poor spatial resolution of the resultant image.
These were reduced with SWT, at the cost of memory requirements Platform: |

Description: This paper proposes new watermarking technique
based on tetrolet domain. The tetrolet transform is a new
adaptive Haar-type wavelet transform based on tetrominoes. It
avoids Gibbs oscillation because it applies the Haar function at
the edge of the image. Our proposed watermarking algorithm
embeds the watermark into the tetrolet coefficients which are
selected by considering different of shapes tetrominoes. We
uated the effectiveness of the watermarking approach by
considering the quality metrics like RMSE, PSNR and
Robustness parameters. The experimental results reveal that the
proposed watermarking scheme is robust against common image
processing attacks. Platform: |

Description: 将要嵌入的多张水印图利用不同正交码调制，之后嵌入到被嵌入图片的小波变换系数中，对小波系数做逆变换，得到已嵌入水印图的图像。利用逆过程可提取出被嵌入的图像(The multiple watermark images to be embedded are modulated by different orthogonal codes, and then embedded into the wavelet coefficients of the embedded images, and the inverse coefficients of the wavelet coefficients are transformed to get the image with embedded watermark. The embedded image can be extracted by the inverse process) Platform: |
